SPECIFICATION formingpart of Letters P fatent No. 530,4 5.8, dated December 4, 1 894.

Application ined March 27, 1894.

To aZZ whom it may concern:

Be it known that I, HENRY REMBERT, a citizen of the United States, residing at Willis, in the county of Montgomery and State of Texas, have invented anew and useful Cotton-Cleaner, of which the following is a speciiication. i

This invention relates to cotton cleaners; and it has for its object toeiect certain improvements in that class of cotton cleaners which are adapted to be arranged in the line of a iiue leading from a gin to a condenser.

To this end the main and primary object of this invention is to add certain improvements to the cleanerclaimed in my former patent, No. 506,134, whereby the dust-laden air will be effectually prevented frompassing through thecleaning drum of the cleaner and mingling again with the cleaned cotton which is fed to the condenser.

With these and other objects in view, which will readily appear as the nature of the invention is 'better understood, the same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described?, illustrated, and claimed.

In the accompanying drawingsz-Figure l is a central vertical longitudinal sectional view of a cotton cleaner embodying the im# provements claimed. Fig. 2 is a transverse sectional view on the line :1cof Figfl.- Fig. 3 is a detail horizontal sectional view on the line 'y--y of Fig. l. Fig. 4 is an enlarged sectional view of a modified form of apparatus.

Referring to the accompanying drawings, A 'represents the enlarged cleaner casing adapted to be arranged intermediate of a cotton gin and a condenser, and said cleaner casing is provided at one end with an enlarged cotton, together with the dust and dirt-laden air, from a cotton gin, while at a directly opposite end the cleaner casing is provided with the contracted cotton discharge flue C, which is adapted to lead into an ordinary condenser in the lint room. Mounted within the cleaner casing A, at a point adjacent to the inner end of the iiue B, is the cylindrical screen cleaning drum D, and at one side of the screen drum D, and adjacent to the inner end of the contracted discharge flue C, is mounted an oppositely rotating combined brush and fan "it reaches the combined vwill be well understood.

`Serial No. 505 ,320. (No model.)

` E, which is adapted to Work in contact with one side of the screen drum, so as to knock oi the cleaned cotton therefrom,

it through the discharge flue C.

The construction just described is the general construction of the cleaning machine de` scribed and claimed in my former patent, before referred to, and it will of course be understood that I employ the screen mote board F, under the combined brush and fan and the bottom mote box G, as set forth in said patent, but in the present invention both opposite ends of the cylindrical screen drum D, are open so as to freely communicate with the upper ends of the opposite inclosed Vertical dust flues H, which "open into opposite sides.

of the cleaner casing, so as to communicate with the interior of the screen drum, and are designed to have their lower ends project through the floor of the gin house so as to carry-off the dust, dirt, andsand. The said screen drum is mounted in any suitable manner, but is illustrated as conveniently mountand impel ed on a centrally arranged shaft disk I, driven by the drum shaft J. Y

Arranged inside of the revolving screen drum D, is a stationary cylindrical shield casing K. The interior shield casing K, extends almost entirely around the interior of the screen drum in close proximity to the screened periphery thereof, and is open at one side as at L, to receive the dust laden air from the flue B, While the cotton carried against the side of the screen drum exposed in the iiue B, is carried around by such screen drum until brush and fan E, as

It `will be readilyunderstood that the interior shield casinglK, cuts od the air current coming from the fiue B, and prevents it passing entirely through the screen drum and mixing again With the cleaned cotton impelled out of the fine C, by the combined brush and fan,

and by reason of thus interrupting the dustladen air currents, the dust and other fine matter passing into the interior of the screen drum nd escape out of the cleaner through the side dust flues H.

The side of the interior cylindrical shield casing K, next to the combined brush and :fan E, is provided with a transverse downwardly disposed dirt slot M, formed between approxi- IOO mately parallel flanges m, and this transverse slot is located directly opposite the point of contact between the combined brush and fan and the screen drum, and it will be apparent that as the combined brush and fan revolves against the screen drum it will cause dirt, sand, dust and other impurities in the cotton to be Worked or rubbed out of the cotton and through the screen drum into the slot M, and thence into the interior of the shield casing, from which they will be carried out through the side dust iiues referred to. y

By substantially cutting off the air current from the flue B, it is necessary to supply the combined brush and fan with clean air, and to accomplish this I employ clean air pipes N. The clean air pipes N, are mounted transversely in opposite sides of the casing and lead from the outer air to a point between the slotted side of the shield casing and the periphery of the screen drum, directly under the slot M, and serve to supply the requisite quantity of clean .air to the combined brush and fan.

The operation involved in the cleaner just described is the same as described in my former patent, and in connection with the improvements claimed I will have it understood that changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

The herein-described improvements may advantageously be embodied in a modified form of machine involving two screen cleaning drums, and -screen condensing drums,

A whereby, in a single machine may be combined more eicient means for relieving dust, dirt, &c., from the lint cotton, and means for conveniently and expeditiously condensing the cotton as it is discharged from the cleaning devices of the machine. In this modication, the cotton receiving flue B, is enlarged to connect with the enlarged casing extension X, that accommodates therein the cylindrical screen cleaning drum D, previously described, and a supplemental superimposed screen cleaning drum D'. The screen cleaning drums D and D', are duplicates in construction, and the second upper drum D', is also provided therein with a stationary cylin'- drical shield casing K', that extends almost entirely around the interior thereof and is open at one side as at L', corresponding to the open side L, of the lower drum D, so as to communicate with the receiving line B, to catch the dust, dirt and sand Without allowing the same to pass entirely through the drum, it of course being understood that the upper superimposed drum D', is open at its ends to communicate with the interior of the l opposite side dust flues H, in the same manner as the lower screen drum D.

Both of the 'drums D and D', are exposed at one side in the flue B, and at the point where the ue opens into the casing of these drums, are located the opposite curved shield flanges O. VThe shield flanges O, are secured to opposite sides of the ue B, and closely embrace the opposite end edges of the drums D and D', and extend therebetween to a point near their point of contact, so as to prevent the air currents from working around and out at the end edges of the drum and also preventing the cotton from clogging at these points. The upper of said drums D', rests directly on top of the lower drum D, and

v is revolved or driven by the frictional contact with sai'd lower drum in a reverse direction to the latter, and as the drums are rotated the cotton is carried around over the top of the lower drum D, in the same manner as inthe single drum cleaner and under the drum D', from which it falls partly in response to the suction of the combined brush and fan E, and the cotton is caught up by the combined brush and fan E and impelledout through the discharge flue C.l

In the modifiation herein described the cotton that is impelled through the ilue C, is forced directly onto'the screen condensing drums P. The screen condensing drums P,

rare mounted to rotate Within the condensing chamber or casing Q, arranged at the outer end of the flue C, as a part of the main casing of the machine, and motion being communicated to the lower of the condensing drums P, the upper drum is driven in an opposite direction by reason of its contact with the lower drum so that as the cotton is carried between said drums it will be condensed and discharged through the discharge opening R, at one side of the chamber or casing Q, said cotton having undergone in a single machine the separate operations of cleaning and condensing.

The screen condensing drums P, are open at both ends and communicate with the op posite vertical side dust lines R', arranged at the opposite sides of the chamber or casing Q, in a similar manner to the other dust iiues H, of the machine.

Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is

1. In a cotton cleaner, the combination with l the inclosed flue casing, the rotary screen drum, and the combined brush and fan at one side of and contacting with said screen drum; of a stationary cylindrical shield casing arrzo ranged inside of the screen drum in close air to the combined brush and fan at the closed side of the shield casing, substantially as set forth.

2. In a cotton cleaner, the combination with the casing, the rotary screen drum, and the combined brush and fan' at one side of the ,g-

drum; of a cylindrical shield casing arranged inside of the drum and communicating with the receiving' flue, and air pipes arranged between one side of the shield casing and the periphery of the screen drum next to the combined brush and fan, to supply the latter with clean air, substantially as set forth.

3. In a cotton cleaner, the combination with the screen drum,and the oppositely rotating combined brush and fan at one side thereof; of a stationary cylindrical shield casing arranged inside of the drum and extending partially around the interior thereof, said casing being provided at one side with a transverse downwardly disposed dirt-slot directly opposite the point of contact between the combined brush and fan and said screen drum, substantially as set forth.

4. In a cotton cleaner, the combination with the flue casing, the rotary screen drum, and the combined brush and fan at one side of and contacting with said screen drum; of a stationary cylindrical shield casing extending partially around the inside `of the screen drum, and provided at a point directly opposite the point of contactbetween the brush and fan and drum with a transverse down- Ward-ly disposed dirt slot, and air pipes arranged outside of the shield casing below said slot and between the casing and said combined brush and fan,substantially as setforth.

5. In a cotton cleaner, the combination with the inclosed fine casing, superposed reversely rotating screen cleaning drums mounted with- `in the casing at the receiving end thereof and provided with open ends, opposite side dust dues communicatingwith the ends of said drums, stationary cylindrical` shield casings arranged within said drums, and open at one side next to the receiving `flue of the casing, and opposite curved shield flanges O embracing opposite end edges of said drums at opposite sidesof the receiving flue of the casing, to prevent clogging of the cotton and the escape of air currents at the end edges of the drums, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

HENRY REMBERT.
